PURPOSE: To produce an ink jet device not closing ink channels or nozzle parts and capable of inexpensively performing ink affinity imparting treatment. CONSTITUTION: Liquid chambers 15 are formed by closing the grooves formed to an actuator plate 11 by a cover plate 20. Manifolds 17a are allowed to communicate with the respective liquid chambers 15 and the nozzles 12a formed to a nozzle plate 12 are allowed to communicate with the liquid chambers 15. A pigment layer 16 is formed to the inner walls of the manifolds 17a, the liquid chambers 15 and the nozzles 12a. Since ink affinity is imparted by the pigment layer 16, the involution of air bubbles is eliminated and ink droplets are made uniform in jet direction and ejected at a stable flight speed. |
